To all whom it may concern:

Be it known that I, GEORGE VILLIAM Mnsoonn, a subject of the King ofGreat Britain and Ireland, residing at St. Agness, 14L castehiau,Barnes, London, S. W., England, have invented certain new and usefulImprovements Relating to Apparatus for Feeding'Web Reels or Rolls inRotary Newspaper Printing and Similar Machines, (for which I have filedapplication in Great Britain, May 16,1919, Patent No. 152,705,) of whichthe following is a specification.

' This invention relates toiapparat'us for feeding web reels or rolls inrotary newspaper printing and similar'machines and relates to suchmachines as are provided with reel carriers adapted to carry a number ofreels and of being rotated or moved to bring the reels into position onthe opposite side of the apparatus in the manner described in thespecification of the prior Patent No. 769659 of 1904. p

According to the invention, I provide each pair of the reel-carryingbrackets for the re ception of two reels and I support the correspondingdriving band or hands upon the brackets in a position between the tworeels so thatthe'same driving band may be used for feeding from one orother'reel mounted upon and between the same brackets. The drivingspindle receives movement through bevel gear from a spindle extendingalong the side of the supporting frame and similarly receiving movementfrom a vertically disposed spindle also at the side of the frame anddriven from a spindle radially disposed with respect to the axis ofrotation of the frame. Means are provided such as described in thespecification of the said prior patent for reversing the movement of thedriving bands according to the position of the reel to be fed withreference to the band.

The respective brackets adapted to carry two reels are disposed oneabove the other in substantially the same manner as in the constructiondescribed in the specification of the said prior patent but therespective brackets are provided of greater strength and of greaterlength, means being provided for the reception of the two reel spindlesinstead of the one. The driving spindle of each driving band is carriedby and between the respective pairs of brackets in a position bewhoselower ends are mount-edon the driving spindle and a weighted lever orother means are provided to permit of the frame thus constituted beingbrought to one side or the other of avertical line passing through thedriving'spin'dle as may be desired according to the particular reel tobe fed, the

arrangement and operation being substantially the same as that describedin'the specification ofthe said prior patent.

on one side, however, a spindleextending alongtheirame is fitted withbevel gears by means of which movement may beimparted from a verticallyvdisposed spindle mounted upon one side of the carrying'frame andsupported therefrom by means" of brackets. Movement is imparted to thespindle last-referred to from a spindle which'extends centrally andtransversely over the rotating base plateon which the frame is mountedand movement is imparted to this spindle in substantia'llythc samemanner as described in thespecification of the said prior patent;

)It will be understood that brackets providedas described for thereception of two reels may be disposed in vertical series on each sideof the carrying frame so that thus the respective brackets on one sideare level with those upon the other and thus four reels are disposedupon the same level, and movement may be imparted to the respectivedriving bands for each set of two reels in the manner described.

The application of the invention is illus-.

supported on rollers or wheels I) so as to turn about a central axis andupon such base member a there is provided a structureor carrying frame acarrying four pairs of brackets 03 arranged in two groups of superposedin the same horizontal plane.

posed pairs, each pair of brackets being adapted to carry two reels'e ofpaper digst a point intermediate and below the bearings for the tworeels on each bracket, there is provided a bearing for the receptionof aspindle f which serves to carry two of the driving pulleys g and also ateach extremity an arm h extending in the upward direction and carryingat a position intermediate and abovethe bearings for the axles of thereels 6 a second spindle 2' upon which is mounted a second pair ofdrivingpulleys g, in positions adjusted with relation to those of thelower spindle in such manner that two driving bands j may be carriedbetween the two spindles f The lower spindle 7 also serves to carry ateach extremity an upwardly directed weighted arm is such that when theupper spindle i is thrown over from the vertical position in eitherdirection, theweighted arms serve to 1 maintain the spindle againstreturn movement and thus to apply pressure of the driving bands upontheparticular reel 6 of paper; I I

At one extremity each of the lower spindles f of the pairs of spindlesis provided with a fixedly mounted bevel gear wheel Z and thebevelwheels of each of the spindles of the one tier are operated through atransverse shaft m arrangedalong the side I of the structure andcarrying bevel gear wheels n in suitable positions to gear with those ofthe spindles. The transverse shafts m relating respectively to the upperand lower series of brackets are preferably con nected together by avertically disposed shaft 0 carrying suitable bevel gears 70. Motion isconveniently transmitted to the 7 lower end of this vertical shaft andalso to the lower transverse spindle m by means of a spindle g at rightanglesthereto extending bands by means of which the web reels arerotated from gear deriving movement from a centrally disposed verticalshaft, the combination of pairs ofbrackets carried by the said frame,which brackets are adapted for the reception of two web reels andseparate driving bands for each pair of brackets, the said driving bandsbeing so mounted as to drive one or other of the web reels mounted onthe respective brackets, substantially as described.

2. In a web reel carrier forprinting machines, of the kind comprisingaframe rotatable about a vertical axis and carrying pairs of-bracketsthereon for the support of the web reel spindles and carrying endlessdriving bands by means of which the web reels are rotated from gearderiving movement from a centrally disposed vertical shaft, thecombinationof pairs of brackets carried by the said frame, whichbrackets are adapted for the reception of two web reels and. separatedriving bands for each pair of brackets, the

said driving bands being so mounted as to drive one or other of the webreels mounted on the respective brackets, and means for causing themovement of the saidrdriving bands from the central vertically disposeddriving spindle, substantially as described.
